Generator problem

Jacksonjack · 06-17-2018, 10:35 PM

I took my PD31 on a trip that was about 6 hours away . Since it was 95 degrees out I decided to run the generator so I could run the rooftop AC . After about 5 1/2 I pulled into a Walmart so Mama could run in and grab some things. After sitting about 10 min the Generator died. The RV had plenty of gas. Tried restarting it and it started but died after 15 seconds. Since we were close to our location I decided not to mess with it. We didn't run it on the way home . The oil level is good. Any ideas what to look for ? Seems weird it would run so long then quit.

Possibly an overheating problem, while underway it got enough air to cool, but not when parked for some reason. If it is overheating, you need to do some troubleshooting as to why. As a start look for anything that might restrict air flow to the generator for cooling.

I agree... This sure sounds like an overheating issue.
Just for fun: check the oil in it. Running them low on oil, is a surefire way to heat them up...

Define plenty of gas. The pickup tube in the gas tank is high enough so it will suck air if the gas tank in not at least 1/4 full. This is by design. Actually most pickups are shorter than that so they suck air 1/3 full. I never let my tank get below the 1/2 full if I am running the generator or plan on running it that day.

I checked the oil and it was good. Plenty of gas as in over 3/4 of a tank. I'm going to fire it up in the morning when it's cool to see what it does after making sure there's nothing blocking air flow .

Where is the generator located on that unit?

This happened to me. Mine always ran fine sitting still or on the highway, then it quit while running. I could crank it but it would die as soon as I released the start button.
Took it to a Cummins/ Onan service center. The brushes had arked and ruined the stator. Fortunately it turned out that these generators have a 2 year / 2000 hour warranty (Parts and labor) (3rd year is major components only) I had owned it 23 months. $1400 it would have cost me if it had happened a month later.
BTW generators are generally NOT covered in the extended warranty that CW pressures you to get.
